Canada’s national laboratory for particle and nuclear physics Laboratoire national canadien pour la recherche en physique nucléaire et en physique des particules Erich W.VOGT, Outstanding Canadian Science Leader (1929-2014) Jean-Michel POUTISSOU TRIUMF Accelerating Science for Canada Un accélérateur de la démarche scientifique canadienne Owned and operated as a joint venture by a consortium of Canadian universities via a contribution through the National Research Council Canada Propriété d’un consortium d’universités canadiennes, géré en co-entreprise à partir d’une contribution administrée par le Conseil national de recherches Canada Erich’s career in brief Early education at U. Manitoba (1951(BSc)-1952(MSc)) The Princeton years( PhD1955) under E. Wigner The Chalk River years ( 1955-1965) UBC and TRIUMF ( 1965-2014) The KAON area ( 1976-1993) • Erich’s legacy; The educator The leader The international expert The team captain June 19, 2014 Erich Vogt memorial session CAP congress 2014 2 Leadership • Leadership is not about driving the train but about laying down the tracks • Examples: • TRIUMF initial funding and organization • TRIUMF as an international laboratory • TRIUMF as a multidisciplinary laboratory • TRIUMF and Technology transfer office • TRIUMF and Universities: expanding the consortium • KAON • Community reach : • Science world • BC science council • Vancouver institute June 19, 2014 Erich Vogt memorial session CAP congress 2014 3 Leadership • At the 1960 Nuclear Physics conference in Kingston, Erich was determined that the proceedings would be issued in a timely manner. • He asked that every speaker come to the meeting with a camera ready version of their presentation. The proceedings were published in record time ( Participants received a truly ” cut, paste and copy” version as they were leaving the meeting) and that procedure was used in many subsequent conferences........................until internet, power point ,etc, returned us to year long proceedings deliveries!!! June 19, 2014 Erich Vogt memorial session CAP congress 2014 4 Erich and me • I started my career in Nuclear Physics recommissioning the Chalk River EN tandem (much admired by Erich ) as it moved to U de Montreal in 1967 • I arrived at UBC in 1972 as a U de Montreal post doctoral fellow to establish its rare decay program and started to build Bl1A at TRIUMF the following year. • I took the position of Research Scientist for UBC in 1978. • 1988-1994: Erich appoints me as his deputy. • As he travelled the world to rally support for KAON, he named me “the director in residence”. June 19, 2014 Erich Vogt memorial session CAP congress 2014 5 The Chalk River years • The Golden Area according to Erich: • Neutron lifetime ( J. Robson) • Muon lifetime and rare decays( Hicks,Pontecorvo) • Solar neutrino search ( Hanna, Pontecorvo) • High resolution Neutron capture Gamma studies • Triple axis neutron spectrometer ( Brockhouse) • Fission fragment neutron emission (Milton, Fraser) • Tandem accelerator ( Bromley, Gove, Litherland) • Li drifted germanium detector ( Ewan, Fowler,Tavendale) • Nuclear Astrophysics ( Al. Cameron) June 19, 2014 Erich Vogt memorial session CAP congress 2014 6 Birth of Nuclear astrophysics • Cameron published his papers on nucleosynthesis in 1957. Experts attribute the birth of the field of nuclear astrophysics to those papers, together with one by a group at Caltech led by William Fowler published the same year. Fowler, an experimentalist, won the Nobel Prize in 1983 for his work in the field, and in his Nobel Lecture credited the independent work of Cameron. • ISAC is now one of the main centres for nuclear astrophysics June 19, 2014 Erich Vogt memorial session CAP congress 2014 7 The Chalk River years • In March 2000, Erich wrote a PIC feature article titled : A century of Canadian Physics- Much to celebrate- • “A strong characteristic of CRNL was extraordinary intensity with which physics was pursued and the correspondingly strong personalities of the physicists involved” June 19, 2014 Erich Vogt memorial session CAP congress 2014 8 Nuclear Physics in the 60’s in Canada . Nuclear physics facilities in the 60’s . McGill Cyclotron 1949 . UBC Van de Graaff 1951 . Queen’s e synchrotron 1950 . McMaster Reactor 1959 . Alberta Van de Graaff 1962 . Laval Van de Graaff 1963 .

McMaster Tandem 1969 . Many of the TRIUMF staff were educated in these centres. June 19, 2014 Erich Vogt memorial session CAP congress 2014 9 The Chalk River years ( end) • “The full blame... ( for the termination of the nuclear physics program at CRNL) ..must be assigned to the lack of vision of AECL, which had forgotten the powerful role that fundamental science can play for its main mission of economic nuclear power. It was a failure of the system, of AECL management and of its prestigious Advisory Councils. It was the same lack of visionary leadership which led to the reduction of fundamental physics at NRC. ( Game score Bureaucrats 2 Canada 0) “ June 19, 2014 Erich Vogt memorial session CAP congress 2014 10 The UBC area • Erich joined UBC in 1965 • Erich as a teacher at UBC (Phys 107) for 45 years earning teaching awards and high ratings from his students ( 5000 by some estimates). • Erich was VP academic for faculty and student affairs (1975-1981) • Erich co-chaired the initial TRIUMF project definition study. Wrote science case, edited proposal and got initial funding. ( more about this from M.Craddock) • Chair of the BOM 1974-1980 • Triumf’s directorship 1981-1994 June 19, 2014 Erich Vogt memorial session CAP congress 2014 11 Erich as UBC VP faculty and student affairs Erich recalled the major challenge he faced then when the Engineering students started a Pie in the face contest . He was asked to deal with the pie throwers who hit the University president. He is remembered for supporting a University women affairs panel to deal specifically with women issues on campus. He strongly supported excellence in teaching and research. He would not have considered the UBC present real estate campaign. Erich was not a fanatic of University politics but more of a team player. He molded TRIUMF to this taste. June 19, 2014 Erich Vogt memorial session CAP congress 2014 12 The TRIUMF area The great leap forward. Erich’s moved to UBC in 1965and took on the challenge of replacing John Warren’s 3MeV van de Graaff by a modern machine that Reg Richardson had just designed for UCLA but did not get funded in the USA. Erich organised the campaign to get a project definition study funded, a proposal written and eventually a cheque from Ottawa. His great connections with Chalk River AECL senior management and government supporters were essential.

P.E.T. June 19, 2014 Erich Vogt memorial session CAP congress 2014 14 Nucleon-nucleon scattering program • The BASQUE experiment, the first experiment in the then new TRIUMF Proton Hall, was a collaboration among the University of Victoria, the University of British Columbia (UBC) and AERE Harwell, the University of Surrey, Queen Mary College and Bedford College in the UK. • Nucleon-nucleon cross sections and spin dependent measurements published by the BASQUE collaboration in 1983 established unambiguous phase shifts for kinetic energies 180 MeV up to 500 MeV. This is still reference data today.
